GHG Data from Inverse Models and UNFCCC National Inventories, 1990-2019

Top emitter countries provide the geographic scope for this collection of greenhouse gas data. It contains five datasets covering CO2, CH4, and N2O fluxes, combining outputs from multiple inverse models with official UNFCCC national inventory reports. The data was compiled by Zhu Deng of Tsinghua University.

Use Cases

• Compare national CO2 flux estimates based on land sector classifications from six inversion models.
• Analyze trends in anthropogenic CH4 emissions using methods from multiple in-situ and satellite inversion models.
• Benchmark inverse model outputs for N2O emissions against UNFCCC inventory data.
• Study sectoral breakdowns of greenhouse gas emissions as reported in national inventories under IPCC categories.

Strengths

• Includes data for three major greenhouse gases: CO2, CH4, and N2O.
• Combines data from multiple sources, including up to 11 satellite inversion models for CH4.
• Covers a long temporal span, with some data series extending from 1990 to 2019.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
